# Missed Call vs Toll-Free vs SMS Short Code

> Missed call number vs toll-free number vs SMS short code in India: who pays, what data you capture, setup effort, literacy needs and cost, with a decision table for each campaign type.

**Short answer:** use a **missed call number** when you only need to know *who is interested*,
a **toll-free number** when the customer needs to *talk to you now*, and an **SMS short code**
when the customer needs to *send you text* (a keyword, a code, a PIN). They are not substitutes;
they capture different things.

## The Three Options Side by Side

| | Missed call number | Toll-free number (1800) | SMS short code / long code |
|---|---|---|---|
| What the customer does | Dials, call is cut | Dials, talks | Types a keyword and sends |
| Who pays per interaction | Nobody per minute | **Business** pays per minute | Customer usually pays SMS cost |
| What you capture | Number + time | Conversation (+ number) | Number + text |
| Staff needed to answer | No | Yes, or an IVR | No |
| Works on basic phones | Yes | Yes | Yes, if they can type |
| Needs literacy | **No** | No | **Yes** |
| Works in any language | Yes | Depends on who answers | Depends on keyword language |
| Attribution per ad | Number per ad | Number per ad (costly) | Keyword per ad |
| Cost grows with volume | Slightly (per event) | **Strongly** (minutes) | Depends on provider |
| Data in real time | Webhook / CSV | Call logs | Provider dashboard / API |

## Missed Call Number

**What it is:** a number that rejects every call with a busy tone. The caller pays nothing and
you get their number and the time. See [what is a missed call service](https://edesy.in/blog/what-is-missed-call-service).

**Strengths**
- Lowest possible effort for the customer.
- Language-neutral: no app, no internet, no typing, any phone.
- No staff needed at the moment of response.
- Cheap per lead, and predictable on an unlimited plan.
- One number per ad gives clean offline attribution.

**Limits**
- You get only a phone number and time. Anything else needs a callback.
- Every call is an event; repeat callers need de-duplication.
- Each number has a cap on simultaneous calls, so bursts need several numbers.

**Typical cost on Edesy:** ₹499/month per number + ₹0.30 per event delivered to a webhook (log and
CSV free without one), or ₹1,498/month Unlimited. Plus GST. See the
[pricing page](https://edesy.in/missed-call-service/pricing).

## Toll-Free Number

**What it is:** a number the caller dials free, while the business pays for every inbound minute.
See [toll-free numbers](https://edesy.in/toll-free-number).

**Strengths**
- The customer can talk to you immediately.
- Signals national scale and removes every barrier to calling.
- Right for support, helplines, recalls and complex sales.

**Limits**
- Somebody, or an IVR, has to answer.
- Your bill grows with every successful campaign.
- Overkill if all you need is a callback list.

## SMS Short Code or Keyword Number

**What it is:** customers send a keyword ("SAMPLE 411001") to a short or long code, and you
receive the sender's number and message.

**Strengths**
- Captures **text**: a code from a pack, a PIN code, a choice.
- Can trigger an automatic reply with a coupon or confirmation.

**Limits**
- Requires typing, which loses low-literacy and older audiences.
- The customer may pay for the SMS.
- Keyword errors and spelling variants need handling.
- Commercial SMS in India comes with registration and template rules.

Edesy does not offer SMS short codes self-serve. If you want an SMS reply to people who give a
missed call, that is **available on request**; we set it up for your account quickly.

## Which One for Which Campaign

| Campaign | Best fit | Why |
|---|---|---|
| Newspaper / hoarding lead capture | **Missed call** | Lowest friction, number per ad |
| TV or radio poll | **Missed call**, several numbers | One number per option, no typing |
| Customer support line | **Toll-free** or local virtual number | Customer needs to talk |
| On-pack unique code redemption | **SMS** | Needs the code as text |
| On-pack interest or registration | **Missed call** | Number is enough |
| Rural or low-literacy audience | **Missed call** | No reading or typing |
| Product recall or safety helpline | **Toll-free** | Zero friction, real conversation |
| Callback request ("we'll call you") | **Missed call** | You call back anyway |
| Event RSVP | **Missed call** | Unique callers = RSVPs |
| Survey with several answers | Missed call (number per answer) or SMS | Depends on how many options |
| High-value B2B enquiry | **Local virtual number** | Buyers expect to speak |

## Cost Comparison, Roughly

Exact toll-free and SMS pricing varies by provider and contract, so check current pricing with
each. The structure is what matters:

| Volume pattern | Missed call | Toll-free | SMS |
|---|---|---|---|
| 1,000 responses/month | Rental + small per-event | Rental + every minute answered | Per-message or pack |
| 10,000 responses/month | Unlimited is predictable | Minutes and staff scale up | Pack or volume price |
| Burst of thousands in an hour | Several numbers, no staff | Needs staff or IVR capacity | Throughput depends on provider |

A missed call number is the only one of the three where **neither side pays per minute and nobody
has to answer**.

## Combining Them

The strongest setups use more than one:

- **Missed call + local number:** "Give a missed call for a callback, or call 0XX-XXXXXXX to talk
  now." The [virtual phone number](https://edesy.in/virtual-phone-number) handles conversations; the missed call
  number collects quiet interest.
- **Missed call + toll-free:** national brands keep toll-free for support and run missed call
  numbers per campaign for attribution.
- **Missed call + SMS reply:** the missed call captures the number; an SMS confirms or delivers a
  code (on request on Edesy).
- **Missed call + CRM:** every caller lands in [Edesy CRM](https://edesy.in/crm) as a lead for the sales team.

## Mistakes to Avoid

- **Using toll-free as a lead-capture line.** You pay for minutes of conversations that a callback
  would handle more cheaply, and someone has to answer every call live.
- **Using a missed call where you need text.** If the offer depends on a code printed inside the
  pack, a missed call cannot carry it; use SMS or a callback that asks for it.
- **One number for every channel.** Whichever option you pick, separate numbers or keywords per
  channel are what make attribution possible.
- **No follow-up plan.** All three capture a moment of interest; only a fast follow-up converts it.

## Decision in Three Questions

1. **Does the customer need to talk to you right now?** Yes: toll-free or a local virtual number.
2. **Does the customer need to send you text?** Yes: SMS.
3. **Otherwise:** a missed call number, with fast follow-up.

## Frequently Asked Questions

### What is the difference between a missed call number and a toll-free number?

A toll-free number answers the call and the business pays for every minute, so you get a conversation. A missed call number rejects the call so nobody pays per minute, and you get only the caller's number and time.

### Is a missed call cheaper than toll-free?

For capturing interest, yes, because there are no per-minute charges. On Edesy a missed call number is ₹499 a month plus ₹0.30 per webhook event, or ₹1,498 a month on Unlimited (plus GST). Toll-free bills you for answered minutes, so cost rises with call volume and length.

### When should I use an SMS short code instead of a missed call?

When you need the customer to send you information, such as a keyword, a code from a pack or a PIN code. A missed call carries no text, only the number and time.

### Can I use a missed call and a toll-free number together?

Yes. Many brands publish a missed call number for quick interest and a toll-free or local number for people who want to talk now.

### Do callers need to be literate to use a missed call number?

No. Dialling a number and hanging up needs no reading or typing, which is why missed calls work across languages and on basic phones.
